To improve the transmission shift feeling during specific operating modes, the Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) calibration has been revised. These improvements include: S Reduced downshift lag when accelerating at speeds from 10 to 20 mph. S Less gear hunting when driving on/off accelerator pedal at 20 to 30 mph (for example: during heavy rush–hour traffic). S Improved response rate during heavy acceleration from a stop. NOTE: S Version 12.2a or later Diagnostic Tester software is required to perform this procedure. S Before proceeding, verify the ECM (PCM) calibration has NOT been updated by checking for the Authorized Modifications Label (shown in step 1 of the Repair Procedure). S Harsh ATM shifting may result if any Repair Procedure steps are omitted (specifically steps 5 and 11 on page 6). Repair Procedure 1. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if ECM (PCM) calibration has been updated. If not the latest ECM (PCM) calibration — go to step 2. 2. Connect the Diagnostic Tester to the vehicle and select CURRENT ECU CAL from the ECU REPROGRAM MAIN MENU. Determine the vehicle’s current ECU calibration (see Figure 2). – The sample screen prints seen below are the 12.1a software version and may differ from subsequent software versions.
